Back[00:00:10]<pfred1> tjb1 I know humanity has finally arrived because now we have remote controlled fire
[00:00:37]<pfred1> that is an awesome movie too if anyone hasn't caught it yet Quest for Fire
[00:00:38]<tjb1> The remote actually has a themostat in it too ;)
[00:00:56]<pfred1> it really puts stuff into perspective for ya

[00:48:34]<tjb1> Asks a question then leaves?
[00:53:39]<RoyOnWheels> what are plasma cutters tolerance now?
[00:54:08]<RoyOnWheels> cutting aluminum seems possible with plasma
[00:55:47]<andypugh> halrun
[00:55:49]<andypugh> Doh
[00:56:24]-!- mhaberler has quit [Quit: mhaberler][00:57:00]<RoyOnWheels> .1mm .05?
[00:57:33]<tjb1> Air plasma has pretty good taper
[00:57:43]<tjb1> .02 per side on .250" thick parts
[00:58:06]<tjb1> but I can cut probably within .010
[01:00:59]<tjb1> Plasma will cut anything conductive
[01:01:00]<andypugh> Unit mismatch here I think.
[01:01:37]<RoyOnWheels> yeah working in mm
[01:02:16]<tjb1> I get .5mm taper per side on 6.35mm thick parts
[01:02:34]<andypugh> I would guess that job-to-job with a CNC the accuracy is limited by the machine, not the process.
[01:03:07]-!- micges [micges!~toudi@acxc206.neoplus.adsl.tpnet.pl] has joined #linuxcnc[01:03:18]<tjb1> My plasma can probably hold within .25mm
[01:03:29]<tjb1> or better once I get it properly set up
[01:05:15]<RoyOnWheels> looking at pretty thin alu, .i think16-.19, looking at router too
[01:05:17]<tjb1> HiDef systems can cut with minimal taper but good luck finding someone with one of those
[01:05:31]<RoyOnWheels> can't afford waterjet unit
[01:05:33]<tjb1> .16-.19mm or 16-19 gauge?
[01:06:33]<andypugh> Laser?
[01:07:20]<RoyOnWheels> had to check, yeah mm maybe even .25mm
[01:07:37]<tjb1> Thats almost aluminum foil lol
[01:07:50]<RoyOnWheels> er
[01:08:04]<tjb1> maybe not but that is thin :P
[01:08:16]<RoyOnWheels> sorry, 1/4 inch thinkness
[01:08:33]<RoyOnWheels> fail on conversion
[01:09:00]<RoyOnWheels> 6mm ish
[01:09:20]<RoyOnWheels> andypugh yeah laser cosf?
[01:09:57]<RoyOnWheels> we'll probably pay a company for now
[01:10:33]<tjb1> Any plasma cutter is going to have significant taper on something that thick

[01:13:39]<RoyOnWheels> and router probably slower then waterjet,laser?
[01:13:43]<tjb1> The higher amperage systems should do it with less, hidef will cut with almost no taper too
[01:14:06]<tjb1> Laser than can cut 1/4 alum is going to be a very large laser
[01:14:21]<tjb1> But laser, waterjet, and plasma are the fastest
[01:14:55]<andypugh> Router will be most accurate, but very very much slower. (and more wasteful)
[01:15:00]-!- slara has quit [Quit: Lost terminal][01:15:18]<tjb1> Might be the cheapest out of laser and waterjet
[01:15:59]<tjb1> My machine will cut .250 alum at 80ipm
[01:16:11]<tjb1> 100ipm max.
[01:16:36]<tjb1> 2050mm to 2540mm a min

[02:28:52]<tjb1> Congratulations!
[02:28:53]<Jymmm> amazon.com ?
[02:29:09]<tjb1> ebay ;)
[02:29:47]<Jymmm> Man, shipping a kid musta been expensive. Just imagine trying to pack the sucker i the box
[02:30:16]<archivist> make it on the cnc
[02:30:49]<Jymmm> he said boy, not Guvenator
[02:33:03]<Jymmm> are the cutters on a pipe threader adjustable? I need to thread the outside of a 2" ABS pipe
[02:33:49]<archivist> some yes some no
[02:34:23]<Jymmm> Ok, thanks. I'll keep my eyes out then.
[02:34:50]<postaL> lol
[02:34:51]<postaL> thanks guys :)
[02:34:52]<archivist> but abs really wants glue
[02:35:08]<tjb1> Lowes has a nice setup where one die will do like .750 up to 1.250
[02:35:16]<tjb1> maybe more
[02:35:49]<Jymmm> archivist: It's not for attachement, but grooves to wind a loading coil and use it as the core.

[02:44:37]<Jymmm> 16ft vertical fishtenna
[02:44:56]<tjb1> What is the purpose of the pipe threads? To wind the coil in?
[02:46:16]<Jymmm> tjb1: http://i46.tinypic.com/2rc7cb4.jpg[02:46:39]<Jymmm> tjb1: in front of the red pipe, but that one is ceramic
[02:46:55]<Jymmm> he pulled if from some old gear.
[02:47:07]<tjb1> Are you just using pipe thread because thats common for 2inch?
[02:47:14]<Jymmm> I want to do 2", 4" , and 6"
[02:47:21]<Jymmm> yeah

[02:49:41]<Jymmm> I'm not sure, I dont think so because it has no guide for the thread itself.
[02:50:18]<Jymmm> I might have to make a ghetto lathe
[02:50:27]<tjb1> I imagine if you tighted it a bit it would cut threads into pvc
[02:50:32]<tjb1> tightened...
[02:51:02]<Jymmm> oh it'll vut them no problem, but it might /// / // / / instead of ////////////
[02:51:15]<Jymmm> cut
[02:51:32]<Jymmm> or even ||||///// ||////
[02:51:51]<tjb1> I see now…no way to advance itself
[02:52:00]<Jymmm> right

[02:52:26]<tjb1> I dont have any other ideas, sorry
[02:52:42]<Jymmm> It's frickin ABS, it wouldn't take much and doens't need alot of force either.
[02:52:57]<tjb1> how critical is the lead?
[02:53:37]<Jymmm> it's not. just consistant for when electrically taping the coil
[02:54:43]<Jymmm> but I can control that by adjusting the speed at which the cutter travels
[02:54:46]<tjb1> You could go to lowes and maybe they will cut it for you
[02:55:23]<tjb1> or maybe get a 2inch pipe coupler, cut it where the threads end and screw the pipe in?
[02:56:10]<Jymmm> I'm really just cutting grooves for the wire to follow is all, not really "threads"
[02:56:17]<tjb1> well 1 1/2 pipe has a 1.9 outside diameter
[02:56:27]<Jymmm> I need 4" diameter too
[02:56:53]<tjb1> 4" has 4.5 outside
[02:56:57]<tjb1> 3 has 3.5
[02:57:18]<Jymmm> yeah, that's no biggy.
[02:57:19]<tjb1> 1 1/2 pvc has a 1.9 outside diameter
[02:57:33]<tjb1> you could probably screw that right into a pipe coupler to get the threads on

[18:28:56]<cncbasher> MAX_ACCELERATION = 60.0
[18:29:05]<cncbasher> under each axis

[18:30:04]<cncbasher> say 5 and 15
[18:30:25]<mevon> cncbasher, since I dont really have control on the speed yet
[18:31:05]<cncbasher> then change your stepgen acceleration to 15x1.25= 18.75

[20:58:29]<c60> also how important is it to have shielded cable for the spindle?
[20:58:50]<mrsun> E.OC.n ? error over current ?
[20:58:57]<mrsun> is the motor overloaded ?
[20:59:03]<mrsun> is the current limit set to low on the vfd ?
[21:02:16]<c60> sorry, E.OC.d, don't think the motor should be overloaded, doing a 6mm pass with a 9mm bit at 2500mm/min
[21:05:01]<c60> max voltage is set to 220 with intermediate voltage at 17, I upped it from the factory default of 15, 2200watt water cooled spindle
[21:15:38]<andypugh> I have visitors the next two weekends, so I have spent all evening making the house loom more like a house and less like a Bat-Cave.
[21:19:00]<andypugh> And I just found a Christmas card, on the mantlepiece. That's been there quite a while.
[21:20:53]<c60> I'm wrong, it's E.OC.n
[21:25:41]<c60> Is the current limit a function of frequency and voltage limits?
[21:25:56]-!- Simooon has quit [Ping timeout: 246 seconds][21:26:10]<t12> is that one of those watercooled chinese ones
[21:26:21]<t12> how is that
[21:26:26]<t12> some guy on ebay sells them?
[21:27:09]<rob_h> sometimes uget a Over current on VFD if u start or stop too fast and Bus can not handle the inrush or outrush current/voltage
[21:27:34]<t12>http://www.ebay.com/itm/CNC-Spindle-for-CNC-Router-2-2KW-/380290226679[21:28:10]<c60> It's one of those watercooled chinese ones, http://www.automationtechnologiesinc.com/products-page/cnc-spindle/2200-milling-spindle[21:29:10]<c60> It starts fine, I've been cutting for a week or two with occasional stops, but I've upped the detect overtorque rating, but today I can barely cut out a 2x2 foot piece without it stopping,
[21:33:07]<t12> bearings feel ok?
[21:33:19]<t12> measure actual current being delivered?
[21:34:38]<c60> bearings seem fine, it doesn't seem to freespin like HSD one I used previously. but feels smooth,
[21:35:04]<c60> problem is it only stalls under load, I can't really measure it when it's running can I? or at least I wouldn't have enough free hands
[21:36:46]<t12> will the vfd display actual current delivered?
[21:37:24]<c60> dont' think so, I had the rated motor current set to 8amp, I upped it to 11, lets see if that works.
[21:39:02]-!- Simooon [Simooon!~simon@gw.obelnet.dk] has joined #linuxcnc[21:39:30]<t12> maybe bearings being weird only when it has load?
[21:39:35]<t12> i'm just making guesses
[21:39:52]<t12> or the vfd is having problems
[21:41:35]-!- skunkworks [skunkworks!~chatzilla@str-broadband-ccmts-ws-26.dsl.airstreamcomm.net] has joined #linuxcnc[21:42:18]<c60> Nope, that didn't work,
[21:42:36]<c60> I wish the error messages were more descriptive.
[21:42:49]<t12> what kinda vfd?
[21:44:42]<andypugh> The manual is probably online
[21:45:13]<t12> might have some bus input or whatnot that lets you read useful values directly
[21:45:19]<c60> from the same website, http://www.automationtechnologiesinc.com/products-page/cnc-spindle/led-display[21:45:34]<c60> 2.2kw
[21:46:20]<t12> looks like you can make it indicate output current
[21:46:52]<c60> hmm, this time the error was E.OC.d which I guess means on deaccelerating, which it wasn't hmmm
[21:47:01]<c60> on the display?
[21:47:06]<t12> yeah
[21:47:19]<t12> page 10 of the pdf
[21:48:02]-!- kmiyashiro has quit [Quit: kmiyashiro][21:48:22]<t12> looks like you can rs485 to it as well
[21:50:42]<c60> so should I run the program again and watch it fail and try to pay attention to the current draw?
[21:51:07]<c60> It's saying .2 -> .4 once it's up to speed, but never goes above 1, this is all without load so far
[21:54:31]<andypugh> Is it perhaps stopping for some other reason, and the OC error is because the run-down ramp is too fast?
